I was about to upgrade from 1.7.3. to 1.83 and run into problems. I just run first step where Environment and server checks was performed. On this page "unicode" appears in RED and as I understand this must be solved prior to going further with upgrade. Then I choosed that I do not want to go further with upgrade, reverted back to 1.7.3 (renamed back 1.7.3 folder for default moodle folder). But now there is a problem as when I login to moodle, admin is not the same, it is like I am logged as user and not admin ! I was about to perform this unicode migration but I can not login as admin anymore. I mean, I can, but in there , there are no settings and moodle stuff. How can i solve this or how can I set this unicode some other way - safe way.
Please help me solve this.
